I have had a pair for a couple of years now, and had no complaints. I frequently leave early or get home after midnight with my job, and I usually kinda coast in, so they're not so loud. Like 69Bonney said, unless you really get on the throttle, they're not going to bother anyone. My biggest concern is warming it up with the choke on, but they're not as loud as a lot I've heard. Besides, they're great pipes and they made a big difference in performance, IMHO.
